Error Analysis of Dual Antenna UAV Tracking System
Aiming at the tracking problem of directional antenna in uav flight detection,this paper studies the principle of using dual antenna for target tracking,and analyzes the tracking system theoretically.In order to ensure the accuracy and reliability of data sending and receiving,and improve the receiving gain and anti-interference ability,the error of uav flying in different longitude and latitude was analyzed,and the relationship between distance d and pitch angle was obtained through simulation results.In order to reflect the tracking effect of the antenna tracking platform in the uav transition field and keep the sampling frequency unchanged,single antenna and double antenna tracking modes were adopted to track,observe the changes of RSSI and further determine that the dual antenna system has advantages of strong capture sensitivity and fast tracking speed compared with the single antenna system.
